golang的makefile編寫

     golang 也需要用到makefile，用makefile編譯生成一個可執行檔案然後執行

TARGET      =   apibin
SRCS        =   $(wildcard *.go)
ALLSRCS     =   $(wildcard *.go ./apis/*.go ./config/*.go ./muduo/*.go ./resources/*.go ./utils/*.go)
VERSION     =   0.0.1
BUILDTIME   =   `date +%FT%T%z`
LDFLAGS     =   -ldflags "-X main.version=${VERSION}"
GCFLAGS     =   -gcflags "-N -l"
#GCFLAGS     =
BINDIR      =   $(PWD)
GOTAGS      :=  -tags static

.PHONY: clean all

all : $(TARGET)

$(TARGET) : % : $(BINDIR)/%

$(BINDIR)/% : $(ALLSRCS)
        go build $(GOTAGS) -v -x $(GCFLAGS) $(LDFLAGS) -o $@ $(SRCS)

clean :
        go clean -i
        -rm $(BINDIR)/$(TARGET)

好用
